Commercial · schools, resorts, homestays
A business never gets a cheap unit.
A home's first hundred units cost under ₹4.25 each. On a commercial meter the first unit costs ₹6.05, and anything serious runs at ₹9.40 — on every unit. That is the whole case for a commercial roof, and almost nobody puts it in front of you.
No cheap slabs. Every unit, full price.
KSEB bills a home in steps — the first fifty units cheap, the next fifty a little more. A commercial connection gets none of that. One rate applies to every unit, and it only goes up.

Average price per unit against monthly usage, from KSEB's Tariff Revision Circular 2025–27. Above 500 units a month the two lines nearly meet — but a business pays the top rate from its very first unit, and most businesses use far more than a home.

At ₹9.40 a unit, a 10 kW roof making about 1,200 units a month returns roughly ₹1.35 lakh a year. And most businesses use their power in daylight — exactly when the panels are producing, so more of it offsets directly.
LT-VII(A) commercial tariff. Hospitals, schools and some institutions sit in other KSEB categories — a clinic bill we show below pays a flat ₹5.85 — which is one more reason we ask for a bill rather than guessing. The fixed charge stays after solar.

Not a tariff table — an actual KSEB bill, with the name taken off. Two things to notice.
- Every unit at one rate. ₹5.85 from the very first unit. A home's first fifty cost ₹3.35.
- The fixed charge is heavy. ₹175 per kW of connected load, every month — ₹1,225 a month on this 7 kW connection, more than a quarter of the bill. Solar removes the energy charge; the fixed charge stays.
This is the hospital-and-institution category (LT-6G). A shop or a resort on the commercial tariff pays more per unit, up to ₹9.40. Different categories, same shape: no cheap slabs, and a fixed charge that doesn't go away.

No subsidy. Something else instead.
The ₹78,000 you may have heard about is a residential scheme. A business doesn't get it — worth knowing plainly before anyone implies otherwise.
What a business gets instead is tax treatment. A solar plant qualifies for accelerated depreciation: a large share of the cost written off against taxable income in the first year rather than spread across a decade. For a profitable business that arrives as real cash, the same year you install.
No subsidy also means no DCR rule. A subsidised home has to use DCR panels, with cells made in India. A business can use non-DCR panels, which cost less — on a net-metered system, if it is commissioned by 31 December 2026. After that the rule is due to tighten, so we’ll tell you where it stands when we quote.
Higher tariff, meaningful tax benefit, no subsidy — and the arithmetic still lands ahead of a home system.
Your accountant will know your exact position better than we do. We'll give them the invoice and specifications they need.
We deliberately don't print a percentage.
- The rate for solar assets has changed over the years.
- The extra allowance applies only to some categories of business.
- It depends on when in the financial year the plant is commissioned.
We would rather send you to your CA with the right question than put a confident number here that turns out not to apply to you.
Daylight businesses, mostly.
Solar suits a building best when its busiest hours and its brightest hours are the same hours. In this district, that describes a lot of places.
SCHOOLS
The near-perfect fit.
Fans, lights, labs and computers running through the middle of the day, on a commercial tariff, under a large uninterrupted roof. One of the best-known schools in Bathery runs on our work.
Holidays are the thing to plan around: the building empties for weeks while the roof keeps generating, so size with net metering in mind rather than peak-day usage.
Because a school's day and the sun's day are the same day, schools are also strong off-grid candidates — a small battery, and no dependence on the line at all.
RESORTS & HOMESTAYS
Where power is a real line item.
Air conditioning, water heating, pumps, kitchens and laundry — a heavy, daylight-weighted load on the highest tariff, where every fixed cost removed shows up in the season's margin.
And guests increasingly ask. A roof that runs on sunlight is worth saying on your listing.
SHOPS · OFFICES · SMALL UNITS
Smaller roofs, same arithmetic.
Anything on a commercial connection with a daytime load — a showroom, a clinic, a workshop, a cold room. The system is smaller and so is the saving, but the ratio that matters doesn't change.
Adoption of commercial solar in Wayanad is still low — not because the numbers don't work, but because very few people have sat down and shown a business owner what they actually spend on power in a year.
That's the conversation we'd like to have with you.
Bigger, but built the same way.
Nothing about our standards changes because the roof got larger: same TATA GI structure, stainless fasteners, 2.5 metre earthing, Mersen, Citel, ABB or Schneider protection, daily monitoring.
- Three-phase connections, balanced properly across phases.
- Larger or multiple inverters, and longer cable runs.
- A proper look at what your truss or slab can carry.
- A different KSEB track for inspection and metering — we handle it.

We don't publish a per-kW rate for commercial work. At this size the roof, the phases and the cable runs genuinely decide the number, and a figure quoted before seeing them would only have to change.
Answered straight.
What do you need from me to give a real number?
Two recent electricity bills and half an hour on your roof. The bills tell us your tariff category, your sanctioned load and how much you actually use; the roof tells us what can be built on it. Everything else is guesswork, and we would rather not send you a guess.
Will it cover my whole bill?
Usually not, and you should be wary of anyone who says it will. Businesses often draw well into the evening, and fixed and demand-related charges don't disappear with the energy charge. What solar does is remove a large, predictable share of the part that keeps rising every year.
Our load is three-phase. Does that change things?
Yes, but only in engineering, not in whether it's worth doing. Three-phase sites need matched inverter configuration and careful balancing across phases. It's normal work at this size — it just needs doing properly, which is exactly where cheap installations come apart.
What about the months we're closed?
This matters most for schools and seasonal resorts. Under net metering your export is credited rather than lost, so an empty building isn't wasted generation — but the way the credit works means it's better to size for your yearly pattern than for your busiest week. It's one of the first things we look at.
Can we claim GST input credit on this?
That one is genuinely contested in Indian tax rulings, and it depends on how the installation is treated for your business. We won't give you an opinion dressed up as a fact — put the question to your CA, and we'll supply whatever documentation they need.
How long does a commercial installation take?
Longer than a home, mostly because approvals and inspection run on a different KSEB track and larger equipment sometimes has to be brought in from outside the state. We give you the honest timeline at quotation stage, in writing, and we would rather tell you twelve weeks and deliver in ten.
Send us a bill.
Two recent electricity bills and we'll work out what your building actually spends on power in a year, what a roof would take off that, and roughly how long it takes to pay for itself. No obligation, and no number until we've seen your roof.
